RESUMEN
Background The emulsification of silicone oil is a significant concern for those with rhegmatogenous retinal detachment (RRD) following surgery. The aim of the study was to assess the frequency of emulsification in the patients who underwent primary vitrectomy and were administered 5000 cs silicone oil. Methodology The Layton Rahmatullah Benevolent Trust in Lahore conducted an ophthalmology study from January 2022 to March 2023. The patients who had primary vitrectomy for RRD with silicone oil tamponade were included regardless of age or gender. Those on anti-inflammatory or steroid medications prior to surgery were excluded. Retinal attachment was examined 8-12 weeks post operation to assess silicone oil removal eligibility. Emulsification occurrence was reported. Data on emulsification time, visual acuity (pre- and post-removal), mean intraocular pressure (IOP), and clinical outcomes were collected and analyzed using the Statistical Package for Social Sciences (SPSS) software (IBM SPSS Statistics, Armonk, NY). The results were graphically presented with mean, standard deviations, frequencies, and proportions. Results A total of 158 patients underwent silicone oil removal after undergoing primary vitrectomy for RRD with silicone oil. The mean age of the patients was 45.90 ± 17.8 years. The mean preoperative intraocular pressure (IOP) among the patients was 16.28 ± 2.97 mmHg. Post removal of silicone oil, the IOP was reduced to 12.66 ± 3.02 mmHg. In 11 out of 158 cases (6.9%) of RRD, emulsification had occurred with silicone oil 5000 cs. We found that out of 11 cases of emulsification, eight (72.73%) were 40 years or older in age. Seven (63.64%) patients had tamponade duration of 10 weeks or longer. However, the difference was not statistically significant. Conclusion In conclusion, our study found that the incidence of emulsification of 5000 cs silicone oil in the patients who underwent primary vitrectomy for the treatment of RRD was 6.9%. We observed that emulsification was more frequent in patients aged 40 years or older and those with a tamponade duration of 10 weeks or longer, although the difference was not statistically significant. Further investigation with bigger sample sizes and extended follow-up periods is required to verify our findings and explore potential factors that could lead to emulsification in this group of patients.
RESUMEN
Background Regardless of the advancements in ophthalmology, rhegmatogenous retinal detachment (RRD) remains a substantial issue for physicians. The present study assessed the incidence of RRD among our population. Methodology A cross-sectional study was performed at the Layton Rehmatullah Benevolent Trust (LRBT) between June 2020 and May 2021. All the patients of RRD, irrespective of gender, within the age bracket of 20 years or more and diagnosed by a consultant ophthalmologist were included in the research study. Patients with serous retinal or tractional detachment and RRD with vitreous leakage were excluded from the study. A slit lamp and dilated fundus examination was performed preoperatively to assess the type of retinal detachment and associated factors as mentioned above. All data were collected on predesigned pro forma. Results About 25,000 individuals were presented to the outpatient department during the study period. Out of these, 100 patients were diagnosed with RRD. The incidence rate of the RRD in our center was 0.4%. There were a majority of the males. The mean age of patients did not vary significantly with respect to gender (p < 0.797). The most common type of RD was the total RD with a frequency of 53 cases followed by inferior RD with 19 cases. The majority of those with total RRD were males, i.e., 37%; however, the difference was statistically insignificant (p = 0.476). The study revealed that most of the RRD was diagnosed in patients < 45 years of age; however, the difference was not statistically significant (p < 0.227). Conclusion The present study highlighted the incidence of RRD and explored the sociodemographic and other clinical features in the Pakistani population. However, it is possible that the RRD condition is still under-diagnosed in our hospital settings. Further exploration is warranted to study comprehensively the risk factors associated with RRD.
RESUMEN
Background Even though significant improvements have been made in the field of ophthalmology, retinal detachment is still an ever-increasing issue in both developing and developed countries. The present study evaluated the risk factors of rhegmatogenous retinal detachment (RRD). Methodology A cross-sectional study was conducted at a tertiary care center between June 2020 and March 2021. A total of 100 patients diagnosed with RRD were enrolled in the study. Patients with inconclusive diagnoses and multiple comorbidities were excluded from the study. A detailed history was taken, including previous surgery and ocular trauma or infections. A comprehensive ocular examination was conducted by an experienced ophthalmologist, including a dilated fundus examination. The causes and type of RRD were documented. Results In the study, a majority of the patients were males, with a mean age of 37.84 (18.29) years and a range of 5-74 years. The majority of those with total RRD were males, i.e., 37%; however, the difference was statistically insignificant (p=0.476). The study revealed that most of the RRD were diagnosed in patients <45 years of age; however, the difference was not statistically significant (p<0.227). The most frequent cause of RRD was lattice degeneration. While 23% of patients with RRD had a history of ocular trauma, uncomplicated phaco was detected in 17 cases. It was found that patients aged less than 45 years more frequently reported ocular trauma as the cause of RRD (p=0.004). Similarly, the cause of RRD was also significantly associated with the type of RRD (p=0.001). Conclusion The present study concludes that lattice degeneration, ocular trauma, uncomplicated, and complicated phaco are the main predisposing factors associated with RRD. Furthermore, the majority of the patients were males in their late thirties. Age, gender, and eye involvement were not significantly associated with the type of RRD.
