Outcomes of primary rhegmatogenous retinal detachment repair among young adult patients

Surgical Outcomes of Rhegmatogenous Retinal Detachment and Fellow Eye Involvement in Adolescent and Young Adult Patients

PURPOSE

To investigate the associations, fellow eye retinal tear or detachment, and surgical outcomes of rhegmatogenous retinal detachments (RRDs) in young adults.

DESIGN

Retrospective consecutive case series.

SUBJECTS

Patients aged ≤ 30 years who underwent surgical repair for RRD between 2014 and 2021 at a single practice. The mean age was 23.85 years (range, 12-30 years).

METHODS

Data collected included demographics, preoperative clinical features of the RRD, visual acuity (VA), type of surgery performed, anatomic outcomes, OCT findings, fellow eye retinal tear or detachment, and postoperative complications.

MAIN OUTCOME MEASURES

Postoperative VA and single-surgery anatomic success rate.

RESULTS

One hundred one patients (109 eyes) were included. Sixty-seven patients (74 eyes) and 17 patients (19 eyes) were followed for ≥ 1 year and 5 years, respectively. The most common associations were myopia (66 eyes, 60.6%), trauma (8 eyes, 7.3%), and prior ocular surgery (7 eyes, 6.4%). Median preoperative Snellen VA was 20/70. The macula was attached in 31 eyes. Scleral buckle (SB) alone was performed in 75 eyes, pars plana vitrectomy (PPV) + SB was performed in 27 eyes, PPV alone was performed in 6 eyes, and cryotherapy with pneumatic retinopexy was performed in 1 patient. Single-surgery anatomical success was 88.7% for SB, 89.7% for PPV + SB, and 75% for PPV. The median final postoperative Snellen VA was 20/50. Twelve patients presented with bilateral RRDs, and sequential surgery was performed in 8 patients, followed by 4 patients who underwent surgery with fellow eye laser barricade. Fourteen patients (13.9%) developed a retinal tear or detachment in the fellow eye, with a mean interval of 8 months from presentation. Of the 17 patients who were followed for ≥ 5 years, 3 patients (17.6%) developed a fellow eye retinal tear or detachment. After initial anatomical success, 6 eyes (5.5%) developed proliferative vitreoretinopathy.

CONCLUSIONS

The most common association of RRD in this study was myopia. Scleral buckle alone was the most common surgical intervention. However, outcomes were generally favorable with SB-only and PPV + SB. Surgeons and patients should be aware of the risk of bilateral retinal detachment and the risk of fellow eye retinal tear and detachment. These patients require long-term surveillance in both eyes.

Outcomes and complications of primary rhegmatogenous retinal detachment repair with pars plana vitrectomy in young adults

BACKGROUND

Scleral buckling has been the standard for rhegmatogenous retinal detachment repair in young patients given the typical lack of posterior vitreous detachment, phakic status, and lower risk of proliferative vitreoretinopathy. In older patients, pars plana vitrectomy alone is typically used for rhegmatogenous retinal detachment repair. We report the outcomes and complications of pars plana vitrectomy for rhegmatogenous retinal detachment in young eyes.

METHODS

Retrospective, single-center cohort study. Medical records of patients between 15 to 45 years of age undergoing primary pars plana vitrectomy for rhegmatogenous retinal detachment repair between 2010 and 2020 were carefully reviewed. All analyses were performed using the Kruskal-Wallis tests for numeric covariates between age groups.

RESULTS

Eyes were stratified by age: 15-24 (group 1, n = 10), 25-34 (group 2, n = 14), and 35-45 (group 3, n = 38). The average number of surgeries were 1.9, 1.4, and 1.1 in groups 1, 2, and 3, respectively (p = 0.004). Single surgery success rates were 50%, 64%, and 92% in groups 1, 2 and 3, respectively (p = 0.005). Final reattachment rates were 80%, 93%, 100% in groups 1, 2, and 3, respectively (p = 0.568). Proliferative vitreoretinopathy developed in 50%, 7%, and 8% of eyes in groups 1, 2, and 3, respectively (p < 0.001).

CONCLUSION

While the final reattachment rates were excellent in all groups, the higher rates of proliferative vitreoretinopathy and lower single surgery success rate in younger patients may suggest that primary pars plana vitrectomy may not be the optimal repair method in these age groups.

How should we report the foveal status in eyes with "macula-off" retinal detachment?

Whilst pre- and postoperative multimodal imaging technologies including optical coherence tomography (OCT) have investigated the morphological correlates of worsened visual outcomes in rhegmatogenous retinal detachment (RRD) with foveal involvement, the nomenclature has adhered to the traditional ophthalmoscopy-based and rather vague term "macula-off". This article appraises the current literature with regard to the preoperative assessment and nomenclature of the foveal status in macula involving retinal detachment (MIRD). A literature review of recent publications assessing functional or morphological outcomes in MIRD was conducted, using the search terms "fovea-off" or "macula-off". The search date was April 28^th, 2021. Original studies in English language were included. Case reports, review articles or letters were excluded. Forty relevant articles (range of publication dates: July 29^th, 2020 - April 18^th, 2021) were reviewed to assess the diagnostic modalities used, morphological parameters assessed, and any specific nomenclature introduced to specify the extent of macular detachment. The results suggest widespread variability and inconsistencies with regard to the preoperative assessment, diagnostic modalities and nomenclature used to describe the foveal status in eyes with RRD termed "macula-off". The extent of macular detachment may be classified by a wide range of morphological parameters, including the height of foveal detachment and the ETDRS grid as overlay tool in OCT devices. There is a scientific and clinical need for an updated nomenclature for eyes with "macula-off" RRD. Preoperative OCT findings should be reported on a regular and standardized basis in order to establish a consensus how to report the foveal status in eyes with MIRD.
