Abstract
Neurotrophic keratopathy is an uncommon degenerative corneal disorder characterized by compromised corneal sensory innervation resulting in the formation of epithelial defects and nonhealing corneal ulcers. Various treatment modalities are available to stabilize disease progression, improve patient well-being, and prevent vision loss. For eligible patients, medical and surgical reinnervation have emerged as pioneering therapies, holding promise for better management. We present a comprehensive review of the disorder, providing an update relevant to ophthalmologists on pathogenesis, diagnosis, treatment options, and novel therapies targeting pathophysiological pathways.

Abstract
Purpose: To evaluate the dimensions of lower punctum in a sample of Iranian normal population using spectral domain anterior segment optical coherence tomography (OCT). Methods: In this cross-sectional study, 102 eyes of 102 healthy volunteers were enrolled. All participants underwent a detailed history and complete ophthalmic examination. Lower punctum metrics were measured using OCT (Spectralis, Heidelberg) with the anterior segment module. External punctal diameter was defined as the largest diameter at the surface of the punctum. Internal punctal diameter was measured at two different depths of 100 μm and 500 μm from the external surface. Measurements were repeated for 30% of data by another grader. The agreement was measured using intraclass correlation coefficient (ICC). Results: The mean age of the participants was 61.5 ± 7.9 years. The mean external punctal diameter was 425.6 ± 124.3 μm. The mean internal punctal diameter at 100 μm and 500 μm was 183 ± 97.5 μm and 77.7 ± 51.4 μm, respectively. The agreement between the graders was high in assessing all punctal characteristics (ICC >0.9 for all measurements). Conclusion: The spectral domain OCT can be used for measuring lower punctum diameter with acceptable reproducibility.

Abstract
Diabetic keratopathy (DK) is a common, but underdiagnosed, ocular complication of diabetes mellitus (DM) that has a significant economic burden. It is characterised by progressive damage of corneal nerves, due to DM-induced chronic hyperglycaemia and its associated metabolic changes. With advances in corneal nerve imaging and quantitative analytic tools, studies have shown that the severity of diabetic corneal neuropathy correlates with the status of diabetic peripheral neuropathy. The corneal nerve plexus is, therefore, considered as an important surrogate marker of diabetic peripheral neuropathy and helps in the evaluation of interventional efficacy in the management of DM. The clinical manifestations of DK depend on the disease severity and vary from decreased corneal sensitivity to sight-threatening corneal infections and neurotrophic ulcers. The severity of diabetic corneal neuropathy and resultant DK determines its management plan, and a step-wise approach is generally suggested. Future work would focus on the exploration of biomarkers for diabetic corneal neuropathy, the development of new treatment for corneal nerve protection, and the improvement in the clinical assessment, as well as current imaging technique and analysis, to help clinicians detect diabetic corneal neuropathy earlier and monitor the sub-clinical progression more reliably.

Abstract
Purpose Surgical punctal occlusion is indispensable for the treatment of severe dry eye in cases where punctal-plug insertion is not applicable due to an enlarged or deformed punctum. However, permanent punctal occlusion is difficult in some cases. In our aim to establish a more reliable punctal occlusion, we have devised a new surgical approach for punctal occlusion. Patients and methods This study involved 20 puncta of 12 eyes of 12 patients (1 male and 11 females; mean age: 65.2 years) with severe aqueous-tear-deficient dry eye. A new surgical procedure for punctal occlusion using fibrous tissue from under the lacrimal caruncle into the diathermy-induced deepithelialized canaliculus as supporting tissue for punctal closure was performed. In all patients, the assessment of eye symptoms, as well as the condition of punctal occlusion by slit-lamp biomicroscopy, tear volume (tear-meniscus radius [TMR] measurement by meniscometry), the condition of precorneal tear film (graded by interferometry [IG]), measurement of fluorescein breakup time (FBUT), and scoring of ocular surface staining (fluorescein score of area [FSA] and density [FSD], and lissamine green score [LGS]) were performed, and the preoperative and 6-month-postoperative values were compared. Results In regard to the postoperative improvement of symptoms, 11 patients showed remarkable improvement, 1 patient showed improvement, and no reopening of the closed punctum was found in any patient. Test values were all significantly improved post surgery (all: P<0.05) as compared to those prior to surgery (respective values [mean ± SD], and the pre- and postoperative P-values were: TMR (mm) [0.18±0.08; 0.56±0.28, P=0.002], IG [4.3±0.9; 2.7±0.8, P=0.009], FBUT [0.4±0.6; 4.1±2.9, P=0.004], FSA [1.6±0.7; 0.7±0.9, P=0.03], FSD [2.7±0.7; 0.6±0.7, P=0.003], and LGS [5.1±2.7; 1.1±2.1, P=0.005]). Moreover, no postoperative complications were observed. Conclusion The findings of this study showed that our novel surgical procedure for punctal occlusion is highly successful and that it results in improved and more complete punctal occlusion.

Abstract
PURPOSE To characterize the microscopic anatomy of the lacrimal punctum and canaliculi in relation to the tarsal plate, muscle of Riolan, and Horner muscle; and to report a novel technique to excise the horizontal canaliculus in severe dry eye patients. DESIGN Observational anatomic study and a retrospective case series. METHODS The microscopic anatomy was studied in 86 eyelids of 25 cadavers (age range: 45-96 years, mean: 79.5 years). Surgery was performed on 18 canaliculi of 7 patients with dry eyes (age range: 37-69 years, mean: 59.9 years). In the microscopic study, 32 eyelids were incised sagittally, 38 eyelids were incised horizontally (1 mm from the eyelid margin), and 16 eyelids were incised parallel to the tarsal plate. All specimens were stained with Masson trichrome. In the surgical group, probe-guided horizontal canalicular excision with incision of the Horner muscle to the lateral edge of the lacrimal caruncle was performed. Both canalicular stumps were cauterized. RESULTS In the microscopic anatomic study, the punctum and the vertical canaliculus were part of the tarsal plate with the muscle of Riolan, whereas the horizontal canaliculus was surrounded by the Horner muscle. In the surgical group, all the operated canaliculi were completely occluded without recanalization 12 months postoperatively. No complications were recorded. CONCLUSIONS Based on microscopic anatomic findings that the lacrimal punctum and the vertical canaliculus are part of the tarsal plate, and that the horizontal canaliculus is surrounded by the Horner muscle, excision of the horizontal canaliculus may be an effective technique to treat patients with severe dry eyes.

Abstract
OBJECTIVE To summarize data on existing and experimental therapies for primary Sjogren's syndrome (pSS), referring both to sicca syndrome and to other systemic disease manifestations. METHODS Relevant English and non-English articles acquired through Medline were reviewed. RESULTS pSS usually has a benign clinical course, centered on sicca features and general musculoskeletal manifestations, and is managed symptomatically. However, a subset of patients develops more severe extraglandular disease that warrants close monitoring and aggressive treatment. For dry eyes and mouth, nonpharmacologic measures to preserve secretions, and tear and saliva substitutes, offer some symptomatic relief. Muscarinic agonists and topical cyclosporine yield well-documented improvement in ocular sicca features. Although traditional antirheumatic drugs are used empirically for polyarthritis and other Sjogren's symptoms, their efficacy in pSS overall and as disease-modifying agents is limited. For the potential severe, nonexocrine manifestations complicating pSS, standard high-dose immunosuppression is used. Among the biologic agents already examined in pSS, those targeting tumor necrosis factor (TNF)-alpha failed to demonstrate significant benefit. Nonetheless, rituximab and other B-cell-depleting therapies appear promising. CONCLUSIONS Treatment of pSS patients with severe extraglandular disease should differ from that of patients with predominantly sicca features and/or general muscoloskeletal manifestations. pSS treatment is mainly symptomatic, primarily directed against sicca complaints. The traditional anti-rheumatic agents show limited efficacy in the systemic process and use of systemic TNF-alpha inhibitors has been very disappointing. B cell depleting treatments and other newer biologic therapies appear more promising.

Abstract
ABSTRACT Corneal ulcers can cause significant loss of vision from scarring and astigmatism, but rapid management can limit the destruction and improve outcomes. Infectious ulcers usually resolve with antimicrobial treatment. Noninfectious ulcers, however, present a diagnostic and therapeutic challenge. They can often be resolved by eliminating toxic medications and providing surface support with lubrication and collagenase inhibitors, but resistant ulcers may need more aggressive therapy with bandage contact lenses, tarsorrhaphy, or autologous serum. Ulcers impending perforation require urgent surgical management (e.g., tissue glue, conjunctival flaps, or keratoplasty). Topical steroids are useful when the ulceration is secondary to inflammatory mediators, but they are contraindicated in corneal melts with minimal inflammation, such as those associated with Sjogren syndrome. Systemic immunomodulation is required in addition to topical therapy in the presence of autoimmune disease. Understanding of the pathological processes that occur in different types of corneal ulcers is essential to formulation of a logical and effective treatment plan. Newer, more targeted treatment modalities may offer treatment options that have greater efficacy and fewer adverse effects.
