Recent indications of endothelial keratoplasty at a tertiary eye care center in South India

Iatrogenic Descemet membrane detachment in the donor lenticule during Descemet stripping automated endothelial keratoplasty

A female patient in her 60s presented with an 8-month history of decreased vision in her right eye. She was diagnosed with pseudophakic bullous keratopathy (PBK), and Descemet stripping automated endothelial keratoplasty (DSAEK) surgery was planned. Intraoperative Descemet membrane detachment (DMD) occurred while inserting the lenticule using the Sheets glide technique. The detachment of the Descemet membrane was detected immediately, and air descemetopexy was performed intraoperatively. Postoperatively, the donor lenticule was attached properly to the stromal bed, except for a focal DMD approximately 3 mm in the inferior part of the lenticule. A second descemetopexy was performed 5 days later, resulting in a complete attachment. A DMD in DSAEK lenticule is an extremely rare complication. Early detection and timely intervention with descemetopexy helped achieve a good anatomical and functional outcome.

Clinical profile and demographic distribution of Fuchs' endothelial dystrophy: An electronic medical record-driven big data analytics from an eye care network in India

Purpose:

To describe the demographics and clinical profile of Fuchs’ endothelial corneal dystrophy (FECD) in patients presenting to a multi-tiered ophthalmology hospital network in India.

Methods:

This cross-sectional hospital-based study included 3,082,727 new patients presenting between August 2010 and December 2021. Patients with a clinical diagnosis of FECD in at least one eye were included as cases. The data were collected using an electronic medical record system.

Results:

Overall, 2570 (0.08%) patients were diagnosed with FECD. The majority of the patients were female (65.53%) and were predominantly adults (99.92%). The most common age group at presentation was during the seventh decade of life with 867 patients (33.74%). The overall prevalence was higher in patients from a higher socioeconomic status (0.1%) presenting from the urban geography (0.09%) and in retired individuals (0.4%). About half of the 5,140 eyes had mild or no visual impairment (< 20/70) in 2643 eyes (51.42%) followed by moderate visual impairment (>20/70 to 20/200) in 708 eyes (13.77%). The average logMAR was 0.61 ± 0.81 at presentation. The most documented corneal signs were guttae (76.63%), corneal scar (23%) and stromal edema (21.73%). The most associated ocular comorbidity was cataract (47.32%) followed by glaucoma (5.39%). More than a tenth of the affected eyes required a surgical intervention of endothelial keratoplasty (15.58%).

Conclusion:

FECD more commonly affects females presenting during the seventh decade of life. Majority of the eyes had mild or no visual impairment and endothelial keratoplasty is warranted in a tenth of the affected eyes.
