Outcomes of cataract surgery in ocular cicatricial pemphigoid

Long-term outcomes of fornix reconstruction and cicatricial entropion repair in ocular mucous membrane pemphigoid and drug-related secondary pemphigoid

OBJECTIVE

To investigate the long-term outcomes of fornix reconstruction and cicatricial entropion repair in patients with ocular mucous membrane pemphigoid (MMP) and secondary MMP.

METHODS

Retrospective chart review of patients with MMP undergoing either fornix reconstruction (with amniotic membrane or buccal mucosal graft) or Wies cicatricial entropion repair between January 1, 2000, and September 1, 2020. Patients had a positive mucosal biopsy and (or) clinical features of MMP or secondary MMP. The primary outcome was overall success of fornix reconstruction based on fornix depth maintenance at latest follow-up. Secondary outcomes included resolution of trichiasis, visual acuity, and improvement of subjective symptoms.

RESULTS

Eight patients (10 eyes) with a diagnosis of MMP (3 males and 5 females; median age, 71 years) and 4 patients (4 eyes) with a diagnosis of secondary MMP (2 females and 2 male; median age, 87 years) were enrolled. Mean follow-up was 22.7 months (range, 0.3-87.5 months) for MMP patients and 15.4 months (range, 3.0-43.9 months) for secondary MMP patients. For MMP eyes, 30.0% underwent fornix reconstruction, 60.0% underwent entropion repair, and 10.0% received both. Re-formation of symblepharon and loss of fornix depth occurred in all MMP eyes at an average of 6.4 ± 7.0 months postoperatively, and trichiasis recurred in all patients at the last follow-up visit. In secondary MMP patients, 75.0% of the eyes showed recurrence of symblepharon, and 66.7% re-formed trichiasis. Both MMP and secondary MMP patients had short-term symptom improvements.

CONCLUSIONS

Fornix reconstruction and cicatricial entropion repair in our cohort of MMP and secondary MMP patients resulted in short-term symptomatic improvement, but recurrence was seen, on average, at 6 months postoperatively.

Visual outcome and postoperative complications of cataract surgery in patients with ocular surface disorders

PURPOSE

To determine the visual outcome and postoperative complications of cataract surgery in patients with ocular surface disorders (OSDs).

SETTING

Tertiary eyecare center in North India.

DESIGN

Retrospective observational study.

METHODS

Patients with various OSDs with stabilized ocular surfaces who underwent cataract surgery during this period and had a minimum postoperative follow-up of 6 weeks were included. The primary outcome measures were postoperative corrected distance visual acuity (CDVA) at 6 weeks, best CDVA achieved, and postoperative complications.

RESULTS

The study included 20 men and 24 women. A total of 55 eyes were evaluated: Stevens-Johnson syndrome (SJS) 35 eyes, ocular cicatricial pemphigoid (OCP) 4 eyes, 8 eyes with dry eye disease (DED), 6 eyes with chemical injury and 2 eyes with vernal keratoconjunctivitis (VKC). The mean duration of OSD was 33.9 ± 52.17 months. The median preoperative CDVA was 2.0 (interquartile range [IQR], 1.45 to 2.0). The median CDVA ever achieved was 0.50 (IQR, 0.18 to 1.45) at 2 months and the median CDVA at 6 weeks was 0.6 (IQR, 0.3 to 1.5). Maximum improvement in CDVA was noted in patients with DED and SJS and the least in OCP. Phacoemulsification was performed in 47.27% eyes with intraoperative complications noted in 9% eyes. Postoperative surface complications occurred in 12 (21.82%) eyes. Other postoperative complications occurred in 9 (16%) eyes.

CONCLUSIONS

Cataract surgery outcome can be visually rewarding in patients with OSDs provided ocular surface integrity is adequately maintained preoperatively and postoperatively.

Cataract surgery in setting of ocular surface disease

PURPOSE OF REVIEW

The purpose of this article is to review the available strategies to successfully identify and manage ocular surface disease (OSD) pre, intra and post-cataract surgery.

RECENT FINDINGS

Cataract surgery and OSD have an intricate relationship: the surgical procedure can induce or exaggerate OSD symptoms, while OSD can negatively impact surgical refractive outcomes and increase the rate of postoperative complications.

SUMMARY

Improving the health and stability ocular surface is the key to enhance post cataract surgery refractive outcomes and avoid complications. This is pivotal for patients affected by severe OSD, but is also important for patients with minimal signs or symptoms. A correct diagnosis and a stepwise approach are the keys to improve the quality of life of such patients.

Vortex Keratopathy as a Presenting Feature of Ocular Mucous Membrane Pemphigoid

PURPOSE

The aim of this study was to describe the presenting feature of vortex keratopathy in 3 patients with biopsy-proven ocular mucous membrane pemphigoid (OMMP).

METHODS

The first patient was a 52-year-old woman with chronic redness and foreign body sensation for 3 years who presented with unilateral vortex keratopathy. Seven months later, in the same eye, she developed conjunctival signs suggestive of OMMP. The second patient was a 33-year-old woman with similar chronic symptoms that were exacerbated by pterygium surgery. Clinical examination revealed vortex keratopathy in the right eye with subtle conjunctival signs suggestive of OMMP. The third patient was a 70-year-old woman with complaints of repeated episodes of redness and foreign body sensation for 18 months who presented with vortex keratopathy in the right eye and conjunctival signs suggestive of OMMP in the same eye. To confirm the clinical diagnosis, bilateral conjunctival biopsy was performed in all patients.

RESULTS

OMMP was diagnosed based on conjunctival signs and confirmed on direct immunofluorescence positivity, demonstrating antibodies characteristic and diagnostic of OMMP in the basement membrane zone. A unique feature that preceded or coexisted with the conjunctival signs was unilateral vortex keratopathy seen in all 3 patients, independent of the stage of the disease at which they presented.

CONCLUSIONS

Vortex keratopathy can be a presenting feature in patients with OMMP. A complete ocular surface examination, especially checking the medial canthus for keratin and the inferior fornix for foreshortening, is necessary. Conjunctival biopsy should be performed in all cases to confirm the clinical diagnosis wherever required.

Perioperative Management and Long-Term Outcomes in Ocular Cicatricial Pemphigoid Patients Undergoing Cataract Surgery

Objective

To observe the outcomes of cataract surgery in ocular cicatricial pemphigoid (OCP) patients and explore routine perioperative medical treatments.

Design

Retrospective case series.

Methods

Fourteen eyes of 8 patients were included in the study. Foster's stage 1-4 OCP patients were given human intravenous immunoglobulin, whereas patients with active inflammation were treated with prednisone tablets and methotrexate. Those who were intolerant to methotrexate and had severe inflammatory symptoms were treated with cyclophosphamide. Cataract surgery was performed for all patients after three months of systemic treatment under stable conditions. The conjunctival biopsy was evaluated by immunofluorescence microscopy. Then, patients were divided into individuals with or without ankyloblepharon. Records were reviewed for OCP stage, type of surgery, best-corrected visual acuity (BCVA), Schirmer I test, corneal fluorescein sodium staining, meibomian gland coloboma range, and ocular surface disease index (OSDI) scores. Follow-up was for the duration of taking topical and systemic medication.

Results

Nine female (64.29%) and 4 male (35.71%) eyes were diagnosed with OCP by biopsy. The mean follow-up time was 60.64 ± 35.62 months. Thirteen eyes (92.86%) of 7 patients underwent phacoemulsification. One eye underwent phacoemulsification combined with amniotic membrane transplantation. The intracapsular extraction of cataract was applied to one eye. The BCVA improved significantly in all the patients, which remained stable until the last follow-up. The Schirmer I test was higher than that before the surgery. Corneal fluorescein sodium staining after surgery showed a decrease in score compared to the preoperative score. The BCVA of the patients after surgery increased significantly. The OSDI scores of patients with ankyloblepharon were significantly higher than for those without it. Postoperative symblepharon showed no significant difference compared to the preoperative symblepharon.

Conclusions

In this series, OCP patients with cataracts were able to undergo phacoemulsification surgery, whereas routine use of immunosuppression and closed postoperative follow-up were necessary.

Chronic cicatrizing conjunctivitis: A review of the differential diagnosis and an algorithmic approach to management

Cicatrizing conjunctivitis constitutes a group of chronic local and systemic disorders that cause conjunctival scarring. A systematic approach is required to sift through the clinical history, examination, and laboratory investigations of patients to arrive at the correct diagnosis of the underlying cause. Establishing the etiology is critical, as the therapeutic approach changes based on the cause of conjunctival inflammation. Effective management of patients with the condition requires knowledge of multiple modalities such as systemic immunosuppressive therapy, use of scleral contact lenses, and surgery for ocular surface and vision improvement. We review the clinical features of this condition and present diagnostic and treatment algorithms to help simplify the complexities in its management. This review attempts to place all the relevant information on chronic cicatrizing conjunctivitis together in one place for the benefit of cornea and ocular surface specialists, general ophthalmologists, and ophthalmology residents.

Cataract Surgery in Dry Eye Disease: Visual Outcomes and Complications

Purpose: To describe the visual outcomes and complications following cataract surgery in dry eye disease (DED). Methods: This retrospective study included 668 eyes of 399 patients with DED, who underwent cataract surgery between 2011 and 2019 at our multi-tier ophthalmology hospital network. Based on etiology, they were divided into three groups: cicatrizing conjunctivitis (CC), meibomian gland dysfunction (MGD), and Sjogren's syndrome (SS). The data on demographics, visual impairment, surgical technique, visual outcomes, and complications were collected using an electronic medical record system. Median LogMAR best corrected visual acuity (BCVA) with interquartile range (IQR) was compared using Wilcoxon's rank sum test. Results: The median age at which cataract surgery was performed was 58 (IQR: 47-65) years. Etiology of DED was CC in 279, MGD in 255, and SS in 134 eyes. Most (471) eyes underwent phacoemulsification, under peribulbar anesthesia (548) through a temporal clear corneal incision (209) with foldable intraocular lens implantation (417). The overall median LogMAR BCVA improved from 1.1 (IQR: 0.6-2.1) at baseline to 0.3 (IQR: 0.1-0.7) and 0.1 (IQR: 0-0.65) at 1 and 6 weeks (p < 0.0001) post-operatively. The median 6 weeks post-operative BCVA was 0.3, 0.1, and 0.1 in CC, MGD, and SS, respectively, and significantly better than at baseline (p < 0.0001). The leading cause of sub-optimal vision was corneal scarring (44; 9%), and the most common complication was posterior capsular rupture with vitreous loss (23; 3%). Conclusion: Cataract surgery has good visual outcomes in patients with DED, without any disconcerting rate of complications. Pre-existing keratopathy is the main determinant of the extent of post-operative visual recovery.

Cataract surgery in patients with corneal opacities

Background

Investigating the efficacy and safety of phacoemulsification with intraocular lens (IOL) implantation in corneal opacities.

Methods

This retrospective study was conducted in a tertiary medical center. Twenty-three eyes of 19 patients with cataracts and corneal opacities obscuring the pupillary center having received phacoemulsification with IOL insertion without any ancillary techniques were enrolled. The primary study outcome measures were uncorrected and best corrected visual acuity (BCVA), and complications. Backscatters of corneal scar lesions were evaluated by slit lamp-based haze grading, Scheimpflug Pentacam and anterior segment optical coherence tomography (ASOCT). Visual outcomes after cataract surgeries and improvement range were used to determine the safety and efficacy of cataract surgery for our patients.

Results

All patients underwent uneventful capsulorhexis and phacoemulsification. The mean age was 72.22 ± 10.1 years, and the mean follow-up period was 18.57 ± 15.42 months. The mean BCVA significantly improved from 1.45 ± 0.65 preoperatively to 0.94 ± 0.55 logMAR postoperatively (p < 0.001), and the number of eyes with a BCVA of 20/100 or better increased from 4 to 14. Complications included corneal edema in two eyes and reactivation of the previous corneal pathology in five eyes. Four eyes did not achieve an improvement in visual acuity after surgery, which may have been due to co-existing ocular co-morbidities. Both Pentacam corneal densitometry and ASOCT demonstrated no significant correlations with final visual outcome. However, a statistically significant relationship between the severity of corneal opacity and improvement range in BCVA (r = − 0.782, P = 0.001) was found by our OCT grading method.

Conclusions

Phacoemulsification and IOL implantation in selected cases of coexisting cataracts and corneal opacities is safe that can provide suboptimal but long-term vision when penetrating keratoplasty is not possible or at high-risk of graft failure. ASOCT is a simple tool to predict visual outcomes after cataract surgery in opacified corneas.
