The punctum was dilated, and the snake-chain stent fed into the nasolacrimal drainage system. The emergence of the stents from the terminal end of the NLD and retrieval with a ball probe was conducted under endoscopic guidance.Results: Bicanalicular nasolacrimal stenting with intranasal retrieval under endoscopic guidance was successfully achieved in six NLDs of three adult cadaveric nasolacrimal drainage systems.Conclusion: Despite being soft and flexible, the snake-chain silicon stent passes smoothly and freely through cadaveric human NLD and is easily retrieved from the nasal cavity. This novel NLD stent design may make stenting of the NLD easier and less traumatic.","PeriodicalId":18740,"journal":{"name":"Middle East African Journal of Ophthalmology","volume":"30 3","pages":"164-167"},"PeriodicalIF":0.5,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11495287/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142504328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective dry eye tests were done, including Schirmer's tests 1 and 2, tear film breakup time, and tear meniscus height (TMH). In this study, patients with one or more positive clinical tests were diagnosed to have dry eyes. Dry eye was graded as mild, moderate, severe, or severe disabling.Results: Among 140 eyes, 79 eyes had pterygium. According to Schirmer's test 1 in eyes with pterygium, 29.1% of the eyes had mild dry eyes, and 26.6% had moderate dry eyes. According to Schirmer's test 2 in eyes with pterygium, 25.3% of the eyes had mild dry eyes, and 26.6% had moderate dry eyes. Tear film breakup time in eyes with pterygium showed a mild dry eye in 25.3% and moderate dry eye in 17.7%. TMH in eyes with pterygium was low at 7.6%.Conclusion: The majority of eyes with pterygium have mild or moderate dry eye according to Schirmer's test 1, Schirmer's test 2, and tear film breakup time. No eyes with pterygium have severe dry eyes. TMH was also low in a small proportion of eyes with pterygium. Dry eye evaluation by Schirmer's test and tear breakup time is, therefore, a crucial clinical tool for early detection and prompt management of dry eye syndrome in pterygium patients.","PeriodicalId":18740,"journal":{"name":"Middle East African Journal of Ophthalmology","volume":"30 3","pages":"149-155"},"PeriodicalIF":0.5,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11495290/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142504327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Change in visual acuity was the main outcome measure. Macular thickness, number of injections, cycles, and visits in years 1 and 2 of follow-up were secondary outcomes.Results: Ninety-six patients with a mean age of 60.9 ± 9.96 years were followed for a mean of 22.17 ± 12.30 months. Ninety-two (95.9%), 3 (3%), and 1 (1%) patients were started on bevacizumab, ranibizumab, and aflibercept, respectively. Of bevacizumab patients, 17 (18.2%) were eventually switched to aflibercept.

Preoperatively, a detailed ocular examination was done, and anterior chamber depth (ACD) and lens thickness (LT) were measured on ultrasound biomicroscopy. Intraoperative and postoperative complications (on days 1, 7, and 30) and best-corrected visual acuity on postoperative day 30 were noted.Results: The mean age of patients was 60.78 ± 9.001 years. The study group consisted of 41.3% of males and 58.7% of females. 8 (19.56%) cases encountered complications during phacoemulsification surgery. The intraoperative complications were capsulorhexis-related in 5 (10.86%) patients, posterior capsular rent in 2 (4.3%) patients, and 1 (2.17%) case had zonular dialysis. There was no difference in mean ACD and LT in cases who developed complications and those who underwent uneventful surgery (P > 0.05). The commonly observed postoperative complications on day 1 were corneal edema (41.3%), anterior chamber flare (45.65%), and cells (39.13%) which resolved with routine topical medications. All patients showed a significant reduction in postoperative intraocular pressure (P < 0.001). A total of 37 (80.43%) eyes regained vision between 6/6 and 6/9 postoperatively (P < 0.001).Conclusion: Phacoemulsification surgery is safe in white mature cataract that results in significant visual improvement. Common intraoperative complications are capsule related, while frequently encountered postoperative complications are corneal edema and anterior chamber reaction. Preoperative ACD and LT have no role in predicting intraoperative complications.","PeriodicalId":18740,"journal":{"name":"Middle East African Journal of Ophthalmology","volume":"30 3","pages":"129-135"},"PeriodicalIF":0.5,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11495291/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142504336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inclusion criteria were gestational age (GA) ≤28 weeks or birth weight ≤1000 g. ROP screening and treatment were done according to the International Classification of ROP guidelines. Treatment was indicated in babies with type 1 ROP or aggressive ROP. Details of ROP screening, treatment, and neonatal risk factors were collected from the records. The results were statistically analyzed, and P < 0.05 was considered statistically significant.Results: The study included 54 babies with a mean GA of 27.47 ± 1.76 weeks and a mean BW of 847.43 ± 189.22 g. ROP was detected at an average postmenstrual age of 33.8 ± 1.7 weeks. The incidence of any ROP and TROP was 87% and 19.14%, respectively. All babies with TROP were managed with laser or intravitreal antivascular endothelial growth factor injection or both. ROP resolved spontaneously in 60%, but those with Zone 2 disease had delayed regression. Inotropic support and anemia were found to increase the risk for ROP.Conclusion: The incidence and outcome of any ROP and TROP in this study are comparable to the rates reported globally, and this reflects the improvement in neonatal care. The use of inotropes and anemia may increase the risk for ROP and needs to be managed judiciously.","PeriodicalId":18740,"journal":{"name":"Middle East African Journal of Ophthalmology","volume":"30 3","pages":"136-140"},"PeriodicalIF":0.5,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11495289/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142504333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
