“…[6,7] There has been only a single published case series comprising of two cases where a combination of argon green laser and Nd: YAG laser has been used to treat premacular hemorrhage. [8] The Nd: YAG laser energy used in these two cases was 3.9 mJ and 5.1 mJ respectively. In our case report, we have used subthreshold energy levels of Nd: YAG laser (2 mJ) as compared to the original case series as well as the routinely practiced energy levels of 3.6-50 mJ.…”

Background: Neodymium: YAG (Nd: YAG) laser and argon laser has been used to treat premacular hemorrhage either alone or rarely in combination. Materials and Methods: We describe a new technique of treating premacular hemorrhage by performing hyaloidotomy using a combination of argon green-Nd: YAG laser. We utilized subthreshold energy levels of Nd: YAG laser of 2.0 mJ as compared to the normal recommendation of 3.6-50 mJ. Results and Conclusions:This technique is easy, effective, and safe to manage premacular hemorrhage. The principle behind this combined laser treatment was to make the internal limiting membrane (ILM) taut by initial exposure to argon green laser, which allowed us to employ the subthreshold energy levels of Nd: YAG laser. We would like to assess the role of this combined treatment modality in comparison to other modalities, including solitary laser therapy in the management of premacular hemorrhage by performing a prospective, randomized long-term study.

“…22 Some previous reports regarding the drainage of premacular hemorrhage by means of argon laser have been published. 22,23 It has been reported that the combination of argon green laser plus Nd:YAG laser has provided relatively less spots and lower energy levels for the treatment of premacular hemorrhage. AGL has been proposed to make the ILM and/or hyaloid more stable and taut for penetration of Nd:YAG laser spots.…”

“…AGL has been proposed to make the ILM and/or hyaloid more stable and taut for penetration of Nd:YAG laser spots. 23 It has been reported that hemorrhage larger than 3 DD with no longer 3 weeks may be a good candidate for Nd:YAG laser hyaloidotomy, but potential risks of the treatment should also be considered. 19 In this study, in order to prevent inadvertent retinal damage, we have paid attention to the size of hemorrhage as well as proximity between the posterior hyaloid and underlying retina on OCT scans.…”

Purpose: To investigate the long-term results and efficacy of the treatment modalities for preretinal hemorrhage due to valsalva retinopathy. Methods: Retrospective review was conducted on 24 eyes of 24 patients with valsalva retinopathy who were treated between 2004 and 2019. These patients were treated with Nd:YAG laser, argon laser and vitrectomy or were only observed. Nd:YAG laser hyaloidotomy was performed in 10 eyes, argon laser was applied to two of those following failed Nd:YAG laser, and vitrectomy was performed in one eye. A conservative approach was adopted in 13 eyes. Results: There were 15 females and nine males with mean age of 41.08 ± 12.72 (21–65) years. Mean follow-up period was 42.83 ± 23.78 (range: 12–116) months. Patients with hemorrhage size smaller than or equal to 4-disc diameter were observed for spontaneous resorption and achieved 20/20 visual acuity within 6 months. Visual acuity of all patients treated with Nd:YAG and/or argon laser, increased within the first week after the treatment. Vitrectomy was performed in only one patient with hemorrhage located away from macula. The good visual outcomes were achieved in all treatment modalities. Conclusions: Observation, Nd:YAG laser and argon laser seem to be safe and effective approaches for eyes with valsalva retinopathy. The size, volume and duration of hemorrhage are the most crucial factors for treatment choice, success and complications.

“…11,12 Argon laser hyaloidotomy for treatment of premacular hemorrhage has been reported as a useful method in a few case reports for treatment of subhyaloid hemorrhage. 7,8 It has not been applied for Valsalva retinopathy in a pregnant patient. Argon laser may be an alternative to Nd:YAG laser due to its availability, focusing capabilities, negligible absorption by ocular media and high absorption by hemoglobin.…”

“…Non-invasive Nd:YAG laser and argon laser membranotomy choices have been proposed as alternatives. [4][5][6][7][8] Laser treatment is a non-invasive method, which enables the drainage of the extensive premacular subhyaloid hemorrhage into the vitreous, facilitates absorption of blood cells and improves the vision within days by clearance of the obstructed premacular area.…”

remacular hemorrhage is a cause of abrupt and severe vision loss that may occur in Valsalva retinopathy and in association with hormonal, metabolic hematological and immunologic alterations.1 Enlargement of the uterus during pregnancy causes an elevation of intra-abdominal pressure leading to elevation in intravenous pressure which decreases venous re- A AB BS ST TR RA AC CT T A 27-year-old female patient had applied to our clinic with a complaint of sudden onset, painless and persistent loss of vision in the left eye starting after an airplane flight 3 days ago. She was 26 weeks pregnant. Visual acuity in the left eye was counting fingers with a normal anterior segment examination. On fundus exam, subhyaloid hemorrhage covering the macular region between the vascular arcades was noticed. After giving information about the pregnancy, complication risks and other treatment alternatives, drainage of the subhyaloid hemorrhage with Argon laser membranotomy treatment was performed. After laser treatment, drainage of the hemorrhage into the vitreous cavity and instant improvement of vision was observed with no complications. The visual acuity was 0.3 (Snellen chart) the following day and 0.9 on the third postoperative day. Premacular hemorrhage was completely drained at one month. No complications were observed on 2 month follow-up. 532 nm lasers are present in most clinics and when proper parameters are selected, it proved to be an effective and safe alternative for treating premacular subhyaloid hemorrhage in our patient.K Ke ey y W Wo or rd ds s: : Lasers, gas; pregnant women; retinal hemorrhage Ö ÖZ ZE ET T Uçak seyahati sonrası sol gözünde 3 gün önce başlayan ani görme kaybı şikayeti olan 27 yaşında 26 haftalık hamile hasta kliniğimize başvurdu. Hastanın görme keskinliği sol gözde 50 santimetreden parmak sayma düzeyinde ölçüldü ve ön segment muayenesi doğaldı. Hastanın fundus muayenesinde sol gözde vasküler arkadların içini tamamen dolduran yarı yarıya seviye veren subhiyaloid-internal limitan membran (İLM) hemoraji tespit edildi. Hastaya hamilelik durumu, uygulanabilecek tedavi seçenekleri ve komplikasyonları ile ilgili bilgi verildikten sonra Argon lazer membranotomi önerildi ve hastanın kabulü üzerine uygulandı. Komplikasyonsuz uygulamanın ardından subhiyaloid-İLM hemorajinin sızıntı şeklinde vitreusa boşalmaya başladığı izlendi. Hastanın ertesi gün görme keskinliğinin 0,3 (Snellen eşeli), postoperatif 3. günde 0,9 olduğu görüldü. Birinci ay sonunda premaküler sahadaki hemoraji tamamen temizlenmişti. Hastanın 2 aylık takibinde görme keskinliği tamdı ve komplikasyon yoktu. 532 nm lazer günümüzde pek çok klinikte bulunan bir cihaz olup, lazer membranotomi uygun parametreler ile uygulandığında hastamızda subhiyaloid-İLM hemoraji tedavisinde etkin ve güvenilir bir seçenek olduğu görülmüştür.A An na ah ht ta ar r K Ke el li im me el le er r: : Lazerler, gaz; gebe kadınlar; retinal hemoraji T Tu ur rk ki iy ye e K Kl li in ni ik kl le er ri i J J O Op ph ht th ha al lm mo ol l 2 20 01 16 6; ;2 25 5( (3 3) ): :1 18 8...
