Cyclodestruction is a technique reserved for glaucomas not controlled with medical and surgical treatment and poor visual potential. During the last century, new cyclodestructive techniques were developed, including cyclophotocoagulation, and the use of continuous-wave diode laser transescleral cyclophotocoagulation (CW-TS-CPC) has become widespread. In recent decades, micropulse diode laser transescleral cyclophotocoagulation (MP-TS-CPC) was introduced. We review the cyclodestruction techniques since their origins and these two techniques of cyclophotocoagulation, which are currently the most widely used: how they are performed, their mechanisms of action and their effectiveness and efficacy. We also review the comparison between them and with other techniques.

This study arises from the need to understand the different therapies for cutaneous squamous cell carcinoma (SCC), especially in challenging clinical situations where conventional therapeutic options may not be optimal.
The purpose of the study is to assess the efficacy and safety of intralesional methotrexate (MTX) as neoadjuvant therapy in the treatment of periocular SCC.
The outcome of a patient after two separate intralesional MTX infiltrations 2 weeks apart is described. Therapeutic response was evaluated, achieving a significant reduction in tumor size and subsequently performing surgical excision of the residual lesion. The procedure was well tolerated, with no local or distant recurrences in the follow up.
Intralesional MTX may be an effective and safe option in the neoadjuvant treatment of periocular SCC. Furthermore, we highlight the growing importance of immunotherapy in the approach to SCC and the need to familiarize specialists with these new treatments.

Marfan and Weill-Marchesani syndromes have a mutation of the fibrillin gene (FBN1), producing alteration of connective tissue, within ophthalmology, it is important to take into consideration this type of diseases in cogenetic alterations in this system will produce modifications at the level of the ocular structures generating problems of various types, Most of the literature refers to ectopia lentis and the complications derived from it, as secondary glaucoma.
We present two patients, one with Marfan syndrome and the other with Weill-Marchesani syndrome, who developed lens dislocation, typical of their pathologies, which led them to undergo different surgeries. Both developed suture dehiscence after these surgeries, as a complication derived from their connective tissue involvement. We thus highlight the need for vigilance and extreme caution in the postoperative period of patients affected by this type of syndromes.

Purpose
To quantify the long-term impact (24 months) on the visual results and activity of neovascular lesions of COVID-19 confinement in patients with nAMD in our population.
Methods
A retrospective observational study of patients with nAMD who attended consultation or were treated during the 3 months before confinement was carried out.
Results
144 patients (168 eyes) with nAMD were included, 51 of them (35.42%) came during confinement, and at 24 months the final cohort was 118 patients (133 eyes).
The previous VA of 57.99 ± 23.68 letters decreased, clinically relevant and statistically significant, by an average of 6.87 (±16.84) and 7.89 (±19.58) at 12- and 24-months follow-up. This change differs significantly from the two-year vision change observed in the national database of pretreated patients.
The median number of injections and consultations is lower in our group at 12 months, compared to the pre-pandemic national database, and tends to equalize at 24 months.
We did not find differences in vision when we compared patients who attended consultations during confinement or in treatment intervals greater than 8 weeks (Tq8w).
Conclusions
The VA of patients with nAMD decreased significantly after confinement, probably due to the lower number of antiangiogenic injections and consultations during the first year, and did not recover during the second year despite the increase in the number of injections and visits close to those reported before confinement.

Background and objective
Woman ophthalmologists of childbearing age are exposed to different types of occupational risks which can be harmful to pregnancy and to the development of the fetus. The objective of this paper is to analyze the perception of these risks during pregnancy.
Material and methods
We designed a survey which was answered by 42 ophthalmologists who had been working during pregnancy. We report the perception of global and specific risk according to the type of agent.
Results
The 38.1% of the ophthalmologists perceive that the overall risk of working during pregnancy is high, and 35.7% consider it moderate. Regarding specific risk, the most relevant agents are the ergonomic and psychosocial ones. Physical agents are considered the least important.
Conclusions
Although most of the surveyed ophthalmologists perceived the occupational risk as high or moderate, only 19% of them took time off work due to this reason. The most important agents were ergonomic and psychosocial.

Aim
To evaluate the efficacy, safety, structural and functional progression following the insertion of iStent inject ® implants in patients with open-angle glaucoma or ocular hypertension at a tertiary-level hospital.
Materials and methods
A retrospective study included 98 eyes (57 males and 41 females) with open-angle glaucoma or ocular hypertension, which underwent iStent inject W® implantation (Glaukos, Corporation, CA) between December 2018 and December 2022. Differences in intraocular pressure (IOP), the number of hypotensive eye drops used, and structural and functional tests were assessed between preoperative values and subsequent reviews during a follow-up period of one (n = 98), two (n = 55), and three years (n = 15) after surgery.
Results
Among the 98 eyes studied, 85% were diagnosed with open-angle glaucoma (50% mild, 32% moderate, and 18% severe) and 15% with ocular hypertension. There was a statistically significant reduction in IOP compared to preoperative values for all visits except the 1-month (p = 0.36) and 3-year (p = 0.39) visits. Visual acuity increased from 0.39 ± 0.25 to 0.72 ± 0.24 (p< 0.01), considering that a significant portion of the interventions included cataract surgery. Before surgery, 66% of the sample used 2 or more hypotensive medications. Post-surgery, the number of hypotensive medications decreased (from 1.88 ± 0.84 to 0.21 ± 0.59 at 3 years) (p< 0.01), with an 88.9% reduction in the number of medications over three years. After surgery, 75% of cases did not require any medication.
Regarding structural and functional tests, thickness of retinal nerve fiber layers (RNFL (p = 0.35), excavation / papilla ratio E/P (p = 0.31), visual function index
(VFI (p = 0.06), and deviation mean (MD (p = 0.06) showed no statistically significant differences post-intervention. However, standard deviation of the pattern (DSM) did exhibit differences, decreasing from 5.46 ± 4.03 dB to 5.34 ± 3.48 dB (p = 0.02).
Conclusion
The results of this study suggest that the iStent inject W® technique constitutes an effective and safe option for tension control and glaucoma treatment.

A thirty-year-old patient attended a few hours after an ocular trauma while hammering, receiving trauma with a metal splinter at the left eye. Due to an unfavorable clinical picture, surgical management was decided, which was initially rejected by the patient. He returned six months later with a profound decrease in left eye visual acuity, reaching counting finger at one meter despite optical correction. The anterior segment shows a lower scarring leukoma, associated with Tyndall (++), retrokeratic pigment, lower posterior synechiae and a total cataract. Cataract surgery with intraocular lens implantation and a posterior vitrectomy with intraocular foreign body extraction were indicated. At postoperative control it was shown that post-traumatic ocular siderosis did not significantly affect his central vision, which remains until now.
