Changes in anterior segment parameters following insertion of ExPRESS mini glaucoma implant vs. trabeculectomy
Conclusions: Both ExPRESS mini glaucoma implant and trabeculectomy significantly decreased intraocular pressure and had transient effects on anterior segment parameters, with minor differences between the methods.RESUMO Objetivo: Comparar as altera ções nos parâmetros do segmento anterior após a cirurgia ExPRESS Mini Glaucoma Shunt vs. trabeculectomia usando a câmera Scheimpflug Pentacam rotativa. Métodos: Neste estudo comparativo prospectivo, 27 pacientes com glaucoma tratados no Centro Médico Rabin de 2009 a 2013 foram incluídos nes te estudo comparativo prospectivo: 19 participantes (19 olhos) foram submetidos ao implante de derivação ExPRESS e 12 (13 olhos) foram submetidos à trabeculectomia. Alterações nos parâmetros da câmara anterior no dia 1 e em 3 meses de pós-operatório foram avaliadas pelas imagens de Scheimpf lug. Resultados: A pressão intraocular diminuiu significativamente em relação aos valores iniciais nos dois grupos. A diminuição nos dois grupos foi semelhante no 3º mês pós-operatório (p=0,82). A cirurgia com ExPRESS causou um aumento temporário do astigmatismo posterior da córnea (p=0, 008) e uma diminuição temporária da profundidade da câmara anterior (p=0,016) e do volume (p=0,006) no primeiro dia do pós-operatório. Ao final de t...

CONCLUSION: Both approaches resulted in similar effective IOP control and accurate intraocular lens predictability. The IOP change affected the postoperative refraction prediction error only in the sequential approach. PMID: 32532540 [PubMed - as supplied by publisher]
In conclusion, optical low-coherence reflectometry revealed differences in biometric factors among the three groups of eyes, with a statistically significantly thinner cornea and thicker lens in the group of glaucomatous patients with pseudoexfoliative syndrome. PMID: 31363329 [PubMed - in process]
Conclusions: AKU is characterized by the accumulation of homogentisic acid in the connective tissues of many organs including the eye. Patients should be carefully examined in ophthalmology clinics in order to not miss systemic diagnoses. It should be kept in mind that AKU may cause iridocorneal angle pigmentation, which leads to glaucoma, and patients should be treated with proper medication when presenting with elevated intraocular pressure values.
This patient has marginal IOP control with advanced glaucomatous cupping and field loss on maximum medical therapy in both eyes, though worse in the left eye. Cataract removal is indicated to improve vision and assist with lowering the IOP. In line with my initial recommendation,1 I would place a standard monofocal IOL (or a toric IOL, if justified by the extent of astigmatism). I would still recommend against placing a multifocal IOL because it would compromise functional vision given the extent of the glaucomatous loss.
The visual fields indicate that this patient has moderate-to-advanced cupping of both optic nerves with more severe cupping in the left eye. Maximum medical therapy over the past 1 to 2 years has resulted in a reduction in the IOP that allowed for disease stabilization. He also has visually significant cataracts in both eyes and wants better CDVA. Therefore, as I did in my initial response,1 I would recommend a monofocal 1-piece acrylic IOL. If significant astigmatism were present in either eye, a toric IOL would have been my recommendation.
Our glaucoma patients are no longer satisfied with spectacle dependence at all distances, surgically induced astigmatism, months long recovery, significant risk for complications, or a procedure that would require them to take multiple glaucoma drops postoperatively. Although, we remind them daily that despite all the advances we have, there is still no magic cure, their expectations are still exceedingly high. Our main goal is to reduce their dependence on drops while offering a quick and safe visual recovery.
This older man has cataracts in both eyes with mild-to-moderate glaucoma in the right eye and more severe glaucoma in the left eye. Similar to my initial recommendation,1 I would perform cataract surgery with a MIGS procedure in both eyes. I would use a monofocal IOL in both eyes. I would not use a multifocal or depth-of-focus IOL in either eye, and I would not do even a mild degree of monovision. If this patient has significant astigmatism in either or both eyes, I would recommend a toric IOL. Femtosecond laser –assisted cataract surgery would be an option for either eye, but he will do well with a manual procedure as well.
3D printed digital contact lenses, bionic eye implants, augmented reality eye condition explainers: the future of vision and eye care are full of science fiction-sounding innovations. Here is where digital health will take ophthalmology in the future! More than 80 percent of perception comes through vision Researchers estimate that 80-85 percent of our perception, learning, cognition, and activities are mediated through vision. Compared to that, our hearing only processes 11 percent of information, while smell 3.5 percent, touch 1.5 percent and taste 1 percent. Don’t you think that’s possible? Renowne...
Conclusions: Favorable refractive outcomes were achieved in the majority of patients despite the potential alteration of preoperative measurements and introduction of error into lens selection when using a combined approach. There does not seem to be a difference in the refractive outcome with regard to the type of glaucoma surgery performed. Control patients who had cataract surgery alone had a higher percentage of achieving target refractive goal and less induced cylinder.
