Abstract: We describe a patient who had uneventful excision of bilateral nasal pterygia using bare sclera technique with adjunctive topical antimetabolite therapy and subsequently developed bilateral corneoscleral dellen. A 44-year old Nigerian male presented with signs of bilateral nasal pterygia and had surgery done on both eyes. The pterygia excisions were performed under local anaesthesia using bare sclera technique with intraoperative adjunctive antimetabolite application. There was no post-operative complication until after 23 days with the appearance of bilateral corneal and sclera dellen, first on the left eye then the right with 5 days interval between both eyes. Treatment modality involved topical lubricant therapy, alternating eye patching and bandage contact lens. Corneal and sclera epithelization occurred in both eyes after six weeks of medical therapy with a slightly inflamed recurrent pterygium in the right eye. Corneal and sclera dellen is a rare late complication of uneventful pterygium excision with adjunctive therapy and it can however be managed effectively by medical therapy albeit increased risk of early recurrence of the pterygium.

Abstract: Corneal collagen cross-linking (CXL) is a photochem therapy for keratoconus, keratectasias and infectious keratitis. Corneal collagen fiber infiltrated with riboflavin, a photosensitizer which generates reactive oxygen species when activated by UVA, was induced to form the cross-links in corneal stroma. The purpose of this paper is to review the basic principle, therapeutic potential of corneal ulcerative disease, existing evidences from laboratory and clinical studies, and relevant limitations, then put forward the advantages of CXL in the treatment of corneal ulcerative disease, and thus provide more possibilities for the treatment of the disease.

Abstract: The aim of this study is to assess patients’ experience and acceptability of an educational intervention run by volunteers to provide information about glaucoma, with the goal of improving patients’ understanding about glaucoma. Clinicians referred patients attending glaucoma clinics at one trust to volunteers for education about glaucoma, surgical or laser interventions and eye drop technique. Patients were subsequently contacted by telephone to complete a satisfaction survey with five responses ranging from strongly disagree to strongly agree. 68 patients were referred to the volunteers over a 7 month period. 27 (40%) were interviewed by telephone. All were happy with their experience of the volunteer service with 23 patients (57.5%) strongly agreeing that they were comfortable speaking to a volunteer, 18 (45%) strongly agreeing that the volunteer was able to answer their questions and explain the condition properly and 22 (55%) strongly agreeing that speaking with the volunteer was a positive experience. 17 (42.5%) strongly agreed that they had better knowledge and understanding about glaucoma and 22 (55%) strongly agreed that they understood the importance regular therapy. Of the 17 patients surveyed about eye drop technique, 14 (82.4%) strongly agreed they were more confident with their technique. Patients were comfortable and accepting of the volunteer scheme and reported better understanding of glaucoma. Using volunteers to educate patients helps clinicians and improves compliance.

Abstract: Introduction: Blood pressure is one of the most important and most widely studied factors affecting the IOP. Another important factor that plays an important role in pathogenesis of glaucoma is cerebrospinal fluid pressure. The present study was planned to study the relationship between intraocular pressure, mean arterial pressure and estimated Cerebrospinal fluid pressure in non-neurological patients. Material and Method: The present study was conducted in the Department of Ophthalmology. The study was carried out as a case-control study for 18 months. The patients above 40 years of age irrespective of sex were included in the study after their informed consent. Total of 250 patients were taken out of which 150 were cases with signs of glaucoma and 100 were controls with no signs of glaucoma. Result: 250 subjects enrolled in the study, a total of 150 (60%) were clinically established cases of glaucoma (with IOP >22mmHg) and comprised the case group of study whereas remaining 100 were apparently healthy subjects with no signs and symptoms of glaucoma and had IOP <22 mmHg and comprised the control group of the study. Mean ICP values of subjects with IOP 31-40 mm Hg were significantly higher as compared to those with IOP 23-30 mm Hg and ≤22 mmHg respectively (p=0.002). Mean Arterial Pressure (MAP) showed a significant near mild positive correlation with IOP (r=0.288; p<0.001) and a moderate positive correlation with ICP (r=0.520; p<0.001). However, the correlation between IOP and ICP was weak positive but significant (p=0.010). The relationship between gender and mean MAP and IOP and ICP was evaluated, and the values of all of them were higher in males as compared to females, but the difference was significant only for mean IOP and ICP (p=0.180 and p<0.001 respectively). Conclusion: The findings in present study thus indicate that the relationship between IOP, ICP and MAP is governed by a multitude of factors (in present study these covariates were age, gender and BMI). The present study was unique in the sense that it was probably the first Indian study exploring relationship between IOP, MAP and ICP, and that too in healthy individuals.
