Background and study aims
This is an observational study. The aim is to compare a ‘23-gauge pars plana vitrectomy (PPV), endolaser, and gas tamponade’ approach versus a ‘vitrectomy alone’ for the management of serous macular detachment associated with optic disc pits. We want to find out about the following questions: Are there differences in the postoperative visual acuity and the postoperative central foveal thickness between two groups? What is the mean time of the postoperative subretinal fluid resolution in both groups? Is there correlation between the preoperative features of the inner/outer segment junction with improvement of postoperative visual acuity?
We would like to show that there a difference between the vitrectomy alone and the combined surgery.
Who can participate?
Patients with Phakic intraocular lens (a special kind of lens) and erous macular detachment associated with optic disc pits.
What does the study involve?
All participants undergo a complete ophthalmological examination - visual acuity, intraocular pressure with applanation tonometry, biomicroscobic examination findings, dilated pupil examination of the posterior segment, optic coherence tomography (OCT), and fundus autofluorescence done – a the begininf were evaluated at baseline and during follow-up period.
Some participants have the 23-gauge PPV, endolaser, and gas tamponade procedure, while others only have the 23-gauge PPV procedure.
What are the possible benefits and risks of participating?

| Study objectives | Are there differences between the clinical outcomes of “23-gauge vitrectomy, endolaser, and gas tamponade” versus “vitrectomy alone” for the management of serous macular detachment associated with optic disc pits? |
| Ethics approval(s) | Ethics Committee of Diskapi Training and Research Hospital, 21/04/2014, reference 15/12 |
| Health condition(s) or problem(s) studied | Optic disc pits (rare congenital anomaly with a reported incidence of one in 11,000 patients) |
| Intervention | Some eyes underwent 23-gauge PPV, endolaser, and gas tamponade (allocated to Group 1) and some eyes of underwent 23-gauge vitrectomy alone (allocated to Group 2). Consecutive cases underwent combined surgery and other consecutive cases underwent vitrectomy alone. All cases were phakic and had serous retinal detachment. |
