Retinal Detachment After Primary Congenital Glaucoma Surgery
Insights
Retinal detachment (RD) occurred in 3.5% of eyes after primary congenital glaucoma (PCG) surgery. Of these, 41% resulted in atrophia bulbi, highlighting a significant complication risk in PCG patients.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Glaucoma Research
Background:
- Primary congenital glaucoma (PCG) is a rare, severe form of glaucoma requiring surgical intervention.
- Retinal detachment (RD) is a known complication following ocular surgery, particularly in eyes with pre-existing conditions.
- Understanding the incidence and risk factors for RD in PCG patients is crucial for improving surgical outcomes and patient management.
Purpose of the Study:
- To determine the incidence of retinal detachment (RD) in eyes that underwent surgery for primary congenital glaucoma (PCG).
- To identify clinical characteristics and surgical factors associated with RD development in PCG patients.
- To report on the visual outcomes and management of RD in this cohort.
Main Methods:
- A retrospective chart review was conducted at Alexandra Main University Hospital.
- Data from 363 children (507 eyes) with PCG who had surgery between January 2005 and March 2019 were analyzed.
- Eyes that developed RD were compared to control eyes regarding demographic, clinical, and surgical characteristics.
Main Results:
- Retinal detachment (RD) occurred in 17 eyes (3.35%) of 13 children (3.58%) with primary congenital glaucoma (PCG).
- No significant differences in intraocular pressure, corneal diameter, axial length, or cup/disk ratio were found at presentation between case and control eyes.
- Case eyes underwent twice as many glaucoma procedures as control eyes, and a statistically significant difference in axial length was noted at presentation and RD diagnosis (P < .001).
- At final follow-up, 7 eyes (41.2%) experienced atrophia bulbi.
Conclusions:
- Retinal detachment (RD) is a significant complication following primary congenital glaucoma (PCG) surgery, occurring in 3.5% of eyes.
- Eyes with PCG undergoing surgery have a higher risk of RD, with a substantial proportion leading to atrophia bulbi.
- Further research into preventative strategies and improved surgical techniques for PCG is warranted to mitigate RD risk.
Purpose:
To report on retinal detachment (RD) in eyes that had surgery for primary congenital glaucoma (PCG).
Methods:
This retrospective chart review took place at Alexandra Main University Hospital. The charts of 363 children (507 eyes) presenting with and having surgery for PCG from January 2019 to March 2005 were reviewed. Eyes that developed RD were enrolled as cases and the remaining eyes as controls. Retrieved data included demographic and clinical characteristics and operative and postoperative follow-up data pertaining to glaucoma (and RD) surgery.
Results:
The records revealed that 17 eyes of 13 children (cases) developed RD (bilateral in 4 children, 30.7%) (3.35% of eyes, 3.58% of children, rhegmatogenous in 15 eyes, 88.2%). The mean ± standard deviation of age at presentation of cases and controls was 4.3 ± 3.8 and 8.1 ± 11.1 months, respectively (P = .22). There were no statistically significant differences in intraocular pressure (P = .76), corneal diameter (P = .22), axial length (P = .98), and cup/disk ratio (P = .45) between case and control eyes at glaucoma presentation. Case eyes had undergone twice as many glaucoma procedures as control eyes. At RD diagnosis, 5 eyes (29.4 %) had their glaucoma controlled and 8 eyes (47.1%) had inoperable RD. Four eyes underwent conventional retinopexy and 4 eyes underwent pars plana vitrectomy with silicone oil. The mean ± standard deviation of follow-up of case eyes was 63.7 ± 56.9 months before RD diagnosis and 45.9 ± 22.3 months after RD repair. There was a statistically significant difference in axial length at presentation and at the diagnosis of RD (P < .001) in case eyes. At the final follow-up visit, 7 eyes (41.2%) had atrophia.
Conclusions:
RD occurred in 3.5% of eyes with PCG that had surgery over 14 years, of which 41% culminated in atrophia bulbi.
